I am an occasional virtualbox user, i just haven't needed a VM yet since installing Manjaro, sometime soon i'll be sure to put pre-built module package in the repo too... but until then anyone can build it (or any module) themselves so long as they have the -headers package is installed, as shown above by masolit. Thanks for posting the instructions here.

I can tell you that any assertions that it is because something cgroups related is not enabled in the kernel config is not what causes the error, as this kernel has everything enabled that the official Manjaro kernel does.

On a sidenote, I don't actually get this error personally as when I gutted pulse out of my system it included the removal of rtkit, since pulse was the only thing requiring it.

Personally, if i did still have rtkit installed and was getting this error, so long as it's not causing any actual problems with the system, i'd just ignore it for now expecting it will get fixed upstream soon.

Korrode will this have the patch on the kernel for bbswitch to be working on my nvidia laptop?

It doesn't.Also the commit patch we revert for the 3.9 kernel fails to revert the 3.10 code.Like how you pointed me to the relevant kernel commit originally, if you find similar information for the 3.10 kernel let me know... but otherwise, you're stuck on the 3.9.11 kernel for now. Lucky it's a good kernel ;p

EDIT: Did Linux 3.4.x bbswitch work for you?You could always just use the official Manjaro linux34 if it works for you, then you still get continued security updates and bugfixes.

3.4 won't even load. I think its due to Haswell.

Let me do some research for 3.10 and let you know if I find anything useful.
